SPECIFICATION forming. part of Letters Patent No. 408,612, dated August 6, 1889. Application filed September 21, 1888. Serial No. 286,032. (No model.)

To all whom it may concern.-

Be it known that we, CYRUS P. GIFFORD and CHARLES A. ALLEN, citizens of the United States, residing at North East, in the county of Erie and State of Pennsylvania, have jointly :invented certain new and useful Improvements in a Childs Adjustable Chair; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, forming part of this specification.

Our invention consists in the improvements in a childs adjustable chair hereinafter set forth and explained, and illustrated in the accompanying drawings, in which Figure 1 is a perspective View of the chair adjusted to operate as a rocking-chair. Fig. 2 is a like view of the chair adjusted to operate as a high chair. Fig. 3 is a detail view showing the attachment of the rear leg of the chair to the rocker, the round E being shown in section. V

Like letters refer to like parts in all the figures. V

In constructing our improved chair the body of the chair A is of usual and ordinary construction. This chair-body A is mounted on a double set of rockers B B and C C, the setof rockers B B fitting between the rockers C C, and beingcentrally pivot-ed thereto by a round I), so that when closed together, as shown in Fig. 1, the two sets of rockers are parallel. To the ears 0 c on the front ends of the rockers C C the lower ends of the front legs of the chair-body A are pivoted, and in the rear ends of the rockers B B is mounted a revoluble round E, through which links or rods of wire F operate. One of these links F from. The rear ends it h of the rockers B are cut off somewhat shorter than the rockers C C, so as to admit of the round 6 being secured between the rear ends of the rockers C C. The rear ends 7th of the rockers B B are also hollowed out, so as to fit the under side of the chair-rounds (1 cl, which rest thereon when the chair is adjusted to operate as a high chair, as illustrated in Fig. 2. The front'ends ofthe rockers B B are also provided with a transverse round g, secured therein. On the front of the chair-legs D D a step or foot-rest H is secured in the usual manner. In operation the chair, when adjusted as'illustrated'in Fig. 1, operates as a childs rocking-chair.

In order to adjust it as a high chair, as illustrated in Fig. 2, the round a is grasped by the hand of the operator, while the foot is placed upon the round 6 at the rear end of the rockers C C. The chair-body A is then lifted up, the links F raising the rear ends of the rockers B B until the rockers B B and C C are opened up, so that the rounds D of the chair-body rest upon the rear ends of the rockers B B, when it operates as a high chair. To adjust it back again, this operation is reversed.

Having thus fully described our invention, so as to enable others to make use of the same, what we claim as new, and desire to secure by Letters Patent of the United States, 1s
